ICAO Annex 15 (Aviation OIS)
Summary
Creates obstruction identification surfaces based on the ICAO Annex 15 specification. These surfaces define areas of airspace around an aerodrome. Each area defines the limits to which an obstruction may project into an airspace. This tool creates surfaces as polygon or multipatch features, or triangulated irregular networks (TINs).
Usage
The Input Runway Features must be Z enabled.
This tool creates the OIS in an existing polygon or multipatch feature class. It can also be generated as a new TIN or polygon shapefile. If a feature class is selected for Output Features, it must have a vertical spatial reference.
Syntax
| Parameter | Explanation | Data Type |
in_features |
The input runway dataset. The feature class must be Z enabled and contain points, polylines, or polygons. | Feature Layer |
highend_clear_way_length |
The length of the area at the high end of the runway, in meters. An aircraft can make a portion of its initial climb over this area. | Double |
lowend_clear_way_length |
The length of the area at the low end of the runway. An aircraft can make a portion of its initial climb over this area. | Double |
out_features |
The output feature class or TIN that will contain the generated obstacle identification surfaces. | Feature Layer; TIN |
Code Sample
The following Python window script demonstrates how to use the ICAOAnnex15 tool.
import arcpy
# set gp environment
arcpy.env.workspace="c:/data/ois.gdb"
arcpy.CheckOutExtension("Aeronautical")
# Input Runway Feature Class
inFeatures = "RunwayCenterline"
# feature class that will contain the OIS surface
outFeatureClass="ObstructionIdSurface"
# exec ICAOAnnex15
